Abstract

PT. Charoen Pokphand Indonesia is a fodder company which is located in Surabaya – Mojokerto Street 26 Km, Krian City. This company consists of 4 areas which are feed mill area, raw material area, silo area, and finished good area. The company was in the preparatory stage SMK3 certification .Companies now want to evaluate the system of K3 with HIRARC that is one of the documents supporting SMK3 certification certification. If the company applies HIRARC, the dangerous activities in the company can be detected and the solution can be made immediately. As a result, the number of the accident in the workplace can be minimized. HIRARC method consists of 3 things which are hazard identification, risk assessment, and risk control. The data which is processed with HIRARC is got from the interview, observation, and company’s data. The result of health and safety evaluation with HIRARC method through PT Charoen Pokphand Indonesia is that there are still many dangerous activities; for example, an activity which has extremely high, high, and normal percentage of risk rating. The percentages of the dangerous activities in silo area are 8,82% in extremely high rate, 14,71% in high rate, and 47,06% in normal rate. On the other hand, the percentage of the dangerous activities in raw material warehouse are 14% in extremely high rate, 35% in high rate and 39% in normal rate. Those dangerous activities must be solved immediately by making risk control. The risk control which is suggested are giving sanctions, making checklist, maintaining the tools, replacing the tools if they are broken, changing the method, and giving training. The potential percentage of the dangerous activities which is expected to decrease in silo area is disappearing the extremely high risk, decreasing the percentage of the high and normal risk to 8,82%, and 23,53%. On the other hand, the potential percentage of dangerous activities which is expected to decrease in raw material warehouse is disappearing the extremely high risk, decreasing the percentage of high and normal risk to15,79% and 21,05%.

Abstract

PT. Integra Indocabinet is a wood furniture company. The company produces two types of products which are set-up product and knockdown product. Each product has monthly target which is set by PPIC department, which is 70 containers per month for knockdown type. However finishing department can’t fulfill this target. The purpose of this research are giving evaluation of actual output in finishing department, and suggesting several ways to improve the actual output. Observation, interview and time study are several methods which are used in this research. Observation and interview methods are used to find the root causes of the problem and to collect the historical data. Stopwatch time study is used to obtain the production capacity at finishing department. The result of production capacity calculation is 64.72 containers, while the actual output is only 62 containers. These capacity value and actual output value are not compatible with PPIC target, which are 70 containers. There are several factors which caused the actual output in finishing department is not optimum, they are the quantity and quality of the raw material from sanding department, higher occurrence of paint replacement, and many defect of WIP components. There are several improvements which are suggested to increase the actual output value. They are utilization of deadline form, classification of similar product in order to reduce the occurrence of paint replacement, and pallet modification to prevent WIP component fell down during production process.

Abstract

Currently, PT. Adicitra Bhirawa wants to increase their production capacity from 120 truck boxes per month into 250 truck boxes per month. The increasing of production capacity is applied by changing their production system from the piecework production system into line production system. The line production system is more efficient than the piecework production system in terms of the worker productivity. Line production system is designed using two heuristic methods of line balancing, Kilbridge-Wester and Helgeson-Birnie. The result shows Kilbridge-Wester gives the better result with 15 workstations. The proposed line production system can achieve the production target and increase the monthly worker productivity from 5.7 truck boxes/worker to 11.9 truck boxes/worker. A proposed plant layout is applied in order to support the new line production system.
